FOLDING KEY-BOARD FOR ORGANS.

SPECIFICATION forming part of Letters Patent No. 464,936, dated December8, 1891.

Application filed June 18, 1891. Serial No. 396 683. (No model.)

lb a whom it may concern.-

Be it known that I, FREDERICK W. HEDGE- LAND, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in FoldingKey-Boards for Organs, of which the following is a specitication.

Figure 1 is a broken-away vertical trans- IO verse section embodying myimproved features, and Fig. 2 a broken-away plan of the stop-actionpart.

This invention relates to improvements in organs and the like, and hasfor its object to provide such musical instruments with a fold ngkey-board and stop-action, as will be herematter set forth.

The present style of organ, with its rigid key-board, is too large to betaken through an ordinary door. By having the key-board and stop-actionfold up the instrument is more easily handled and takes up less roomwhen not in use.

Referring to the drawings, A represents the 2 5 organ-case, B thekey-board, and O the stopaction part or frame. The key-board is hingedto the case, as at a, and folds upwardly, the outer edge following thedotted line a. The stop-action frame O is provided at each end 0 with apivot pin orscrew 1), which, being inserted in the interior ends of thecase, permits of the frame folding upwardly and inwardly on the line b.The stop-stems a are each provided with the pivot-joint b and arethereby adapted to follow the movement of their frame in its change froma horizontal to a vertical position. Theinner edge of the locking-platecl is secured to the stop-action frame and moves therewith. When thefold- 0 ing parts are in position for use, as shown in Fig. 1, the plate01 covers the line of separation between the key-board and stop-actionframe and looks or holds the key-board in its open position, so that thestop-action must first be moved before the key-board can be folded up.

The opening in the case above the keyboard, necessaryin this form ofconstruction, is closed by means of the drop door D, hinged to theinside front, as at d. The lower end of this door rests loosely on thecoveringboard g of the stop-action frame and moves upwardly therewith online h.

The key-board and stop-action fold inside of the case, thus reducing thewidth of the instrument to the diameter of the case proper, so that itwill easily pass through an ordinary door.

Having thus described my invention, What I claim as new, and desire tosecure by Let- 5o ters Patent, is-

1. An organ or like musical instrument provided with a folding key-boardadapted to fold inside of the case proper, substantially as and for thepurpose set forth. 6;

2. An organ or like musical instrument provided with a foldingstop-action, substantially as described.

3. In an organ, the combination, with the inclosing case, of thestop-action frame hav- 7o ing its respective ends pivoted to thecorresponding ends of said case, and the stopstems, pivoted as at 1),whereby said parts are adapted to be raised upwardly out of the way ofthe folding key-board, substantially as described.

4. In an organ, the combination of the folding key-board, the foldingstop-action, and the locking-plate secured to the stop-action frame,substantially as described. 8o

5. In an organ, the combination, with the inclosing case, of the dropdoor hinged thereto and adapted to close the opening above the keyboardand stop-action when the same are turned downwardly in position for use,substantially as described.
